Name

net node traceroute -  traces the route to another node

Synopsis

traceroute <addr> 

Arguments

addr

destination node

Description

This command traces the route from one node to another, much like the classical traceroute networking utility. It sends ICMP echo-request messages from the source note to the destination node with an increasing TTL value.

The following example illustrates how to use the traceroute command: cbgp> net node 1.0.0.0 traceroute 1.0.0.4
  1 1.0.0.1 (1.0.0.1) icmp error (time-exceeded)
  2 1.0.0.3 (1.0.0.3) icmp error (time-exceeded)
  3 1.0.0.4 (1.0.0.4) reply
cbgp>

Although the traceroute command sends its probes with the same mechanisms (same protocol stack) as other messages in the simulation (especially BGP), the messages sent by traceroute are put in a separate simulation queue which is processed immediately. This is the reason why there is no need to run sim run to process traceroute's messages.
